I managed to get some work done on the dry-fire mechanism today.
The design is same-old, same-old, but for its position.
If you look closely, you can see that the dry-fire falls into the trigger mechanism,
giving it support at the base of the latch as well as at the top.
Even though the two screws holding top rail in place are very large
and strong, I was concerned about the force of the string hitting the
dry-fire latch and dislodging the top rail.
This has been overcome with the latch been almost vertical and supported from the top and bottom.
The top rail will also double as a sight support and a connection point
for the bolt retaining spring.
I added a piece of timber to the rear of the trigger to support the dry-fire device. If you look closely at the photos you will see
two 2" dowels, running through it, into the stock.
Looks solid, I like how the dry-fire catch dips into the trigger housing and rests on the spacer. If it ever does go off unintentionally, it doesn't look like it will go any further, because the point of contact is level with the anchor point of the plate and the fulcrum of the actual catch is below that, thus it should actually try to pull the plate forward...not up or down. So, thumbs up on that bit. :)

*however*
ReplyDeleteThe angle at which the catch contacts the spacer isn't exactly working in your favor, but if you will be using one of those fiberglass prods which are mounted under an angle, then that might be the exact compensation needed to keep the force oriented properly for everything to function in balance.
Anyway, interesting build. The more you explore it, the more you will actually feel the forces within your assemblies. Yeh, most of the build happens in the head. :)))
Good luck,
